Two new N-oxide alkaloids with pyrrolo[1,2-α]azepine skeleton, namely isoneostemocochinine-N-oxide (1) and neostemocochinine-N-oxide (2), as well as three known alkaloids with pyrido[1,2-α]azepine skeletons, were isolated and identified from the roots of Stemona cochinchinensis (Stemonaceae). The structures of these compounds were elucidated by 1D- and 2D-NMR spectra and other spectroscopic stu...

Despite a favourable morphology, anodized and ordered TiO2 nanotubes are incapable of showing electrochromic properties in comparison to many other metal oxide counterparts. To tackle this issue, MoO3 of ~5 to 15 nm thickness was electrodeposited onto TiO2 nanotube arrays. A homogenous MoO3 coating was obtained and the crystal phase of the electrodeposited coating was determined to be α-MoO3. T...

In this study, the relationship among four species of Polygonum (including P. hyrcanicum (three samples), P. persicaria, P. avicular, and P. hydropiper) was investigated by GC profiling. Furthermore, the major compounds of the ethylic ether extract of P. hyrcanicum were identified by GC/MS as: α-bisabolol (17.5%), cedrol (15.9%), sesquisabinene hydra...

Background:Ocimum forskolei and Teucrium yemense (Lamiaceae) are used in traditional medicine in Yemen. Methods: The chemical composition, antimicrobial, antioxidant and cytotoxic activities of the essential oils isolated from the leaves of Ocimum forskolei Benth. (EOOF) and two different populations of Teucrium yemense Deflers., one collected from Dhamar province (EOTY-d), and another collecte...

in this study, the essential oil obtained by hydrodistillation of the seeds of vitex pseudo-negundo (verbenaceae), growing wild in sabzevar, khorasan razavi province, iran, were analyzed by gc and gc/ms. the yield of total volatiles was 0.8% (w/w). thirty-seven compounds representing 92.4% of the seed oil were identified. the main components of the oil were hexadecanoic acid (8.0%), elemol (7.0...

α-Interferon is an antiviral agent used in treatment of chronic hepatitis B. Triggering of the underlying autoimmune disease or exacerbation of pre-existing auto immune disease is documented with α-interferon, but there are few reports about occurrence of autoimmune disorders such as systemic lupus erythematosus, Vitiligo, hypo and hyperthyroidism after administration of α-interferon in the lit...

α-Fe2O3 (hematite) is the most stable iron oxide under ambient conditions. This transition metal oxide has been extensively investigated because it has unique electrical and catalytic properties. In this report, a novel microwave method for preparation of α-Fe2O3 nanoparticles has been developed. The process contained two steps: first, precursor were obtained from a mixed solution of 50 ml of 0...

Earth abundant transition metal oxides are low-cost promising catalysts for the oxygen evolution reaction (OER). Many have shown higher OER activity than noble (RuO2 and IrO2). experimental theoretical studies been performed to understand mechanism of OER. In this review article we considered four earth oxides, namely, titanium oxide (TiO2), manganese oxide/hydroxide (MnOx/MnOOH), cobalt (CoOx/...

Globally, gastric ulcer is a vital health hazard for a human. Rabdosia inflexa (RI) has been used in traditional medicine for inflammatory diseases. The present study aimed to investigate the protective effect and related molecular mechanism of RI using lipopolysaccharide (LPS)-induced inflammation in RAW 246.7 cells and HCl/EtOH-induced gastric ulcer in mice. We applied 3-(4,5-dimethyl-thiazol...
